He can't simply flip the wheels, as the 3x5 L shaped liftarms obviously can't fit inside the rim.

You're going to have a huge Ackerman situation going on there as well! Intentional?

[TheItalianBrick]

Well I mean not keeping the same architecture of course…..I thought that was obvious tho!

actually he can flip the 3X5 lift arms aswell and use a 7L rack plus something else to reach 9 studs length

[Dave21]

Nice but you have a big problem…the steering point it's way to far from the wheel.

Also, using hubs you can reduce it by 2 studs…..

P.S. cool renders! What software are you using??

Thanks

I don´t use hubs, because I haven´t enough of them for 4 axles... And I don´t want to buy more atm.

I am using "BlueRender", for more information you can look at this thread: http://www.eurobrick...howtopic=109972

I though that way also... but in a test chassis with 4 axles it worked quite well...

Yes, I could flip the 3x5 liftarms, that´s something I didn´t consider before... Now I need to make a version 2.0

flip the entire hub assembly, like this:

I have used that setup in many mocs and it works great. It can be adapted to many builds.

Your picture is to small and nothing to see... can you repost the better one? Thanx... :)

Hi!

I'm new here, but does anyone have a front axle that doesn't require specialized parts except for a gear rack and linkages? and suspended?

Edited December 4, 2015 by flyboy01

[efferman]

space between tires? what it should can do?

[piterx]

Here is a pretty reliable independent floating rear suspension module I did a few weeks ago..

GENIUS.

[kb7]

Has anyone been able to design an extremely compact axle with steering and drive that is only 11 studs between the wheels yet? It doesn't need suspension and I am using 13x24 wheels.

kb7, should it be suspended? You mean 11 studs between pivot points?

From recent discoveries, Thirdwigg's Audi Allroad has steered, driven, suspended independent suspension. But without a differential.

My MB 2045 truck has rigid steered and driven suspension, including differential. I believe it would be quite easy to make it suspended, if needed.

[kb7]

I just edited my last post kind of late, sorry but I don't need differentials and there is no need for it to be strong or pretty.

[syclone]

My first successful design of a front suspended and differential driven axle.It has positive caster angle.

LDD doesn't wants to connect the links , but I built it in real life and everything works smoothly.

Currently I'm building a Nissan Skyline GT-R R34 and it has all wheel steering and drive, so I needed that setup.

Desiged to work with these wheels

I haven't seen these in this collection yet: Double wishbone suspension with longitudinal torsion bar. From an AWD-platform I'm building.

Front module

Main characteristics:

+ Driven axles with differential

+ 4 stud suspension travel

+ 5 stud clearance (with 94.8 x 44 R balloon tire)

+ Progressive camber angle

+ Caster angle

+ Kingpin inclination

+ Ackermann steering

+ Tweakable torsion tension

+ Prepared for carrying a V12 engine

Rear module

Main characteristics:

+ Driven axles with differential

+ 4 stud suspension travel

+ 5 stud clearance (with 94.8 x 44 R balloon tire)

+ Progressive camber angle

+ Tweakable torsion tension

+ Prepared for carrying a V12 engine

The caster angle is a good idea, but there are a few other things that I would design differently:

- The track rods (links) are very angled. this makes steering sloppy, especially during turns. I would try to place the tooth rack closer to the axles, see also LPEpower's video (at 2:15):

- The shock absorbers are attached to the lower suspension arm, which may cause the lower suspension arm to get disconnected from the wheel hub when riding over a bumpy surface. I would try to find a setup with the lower suspension arm placed up-side-down or I would try to apply the shock absorber to the upper suspension arm, for instance in a push rod style (horizontally placed, see for instance: http://www.sheepo.es...hbone-with.html).

Good luck!

Hello All,

I fell in love with the 49,5x20 tyre, and wondered what could be the smallest 4x4 chassis with steering for it.

Here is my solution, haven't tested yet in practice (only an one stud wider version, which works fine).

Hope, it will come handy, theoretically also can be motorized, I suggest with Minizip cable and 9V battery.

or for concept with motors (not connected) CLICK.

@agrof I love the look of that chassis - its so small and cute!

[syclone]

Will build and see how performs :)

[agrof]

There might be a small issue with the steering, I am unsure if the play between the beams offer enough steering angle. In worst case, the toothbar must be moved one stud forward, this is what I did for my 10 stud wide version (this is 9 stud). The 11 stud wide first concept I have built, worked flowless with this setup, as in LDD file. Enjoy!

You are completely right, there isn't enough play , have no idea how to make it one stud longer Edited April 16, 2016 by LXF

[agrof]

Thanks LXF for the prompt test, I made a quick update, so the toothbar is moved forward by 1/2 stud. Still theory, but should work better, could You check it please?

(I am working further on the 10 stud wide version, only because the drivetrain can be placed centered on it.)

Original post is updated.

EDIT:

10 stud wide version is ready, built, tested, for LDD file CLICK.

The only "disadvantage", that it looks with 56x26 wheels better.

In reality for the steering gear's axle You can put 1 stud bushing as spacer, instead of the 1/2 bushing.

And another 9 stud wide version here, driven by worm gear.

After having an idea with small bevel gears, I looked for benchmarks, and found that I wasn't alone. EFFEUNO471 made a similar concept a while ago - see here.

I created my version too, to be honest, I have no clue how to motorize it in a compact way, but was an interesting experiment.

Sorry , can't test this one because I don't own those old steering arms :(
